Side outlet sump connection: For shipping purposes, sumps are at-
tached upside down in the basin to prevent damage. Sumps are to be
installed in the square opening in the floor of the cold water basin of one
or more cells—sealed against leakage, and attached by machine bolts,
according to the installation drawing included. An appropriately sized
circular opening in the vertical face of the sump has been drilled to 125#
ANSI B16.1 flat-face flange specifications. A full faced gasket and ap-
propriately sized bolts (by others) must be used for proper distribution.
11. Attach makeup water supply piping to appropriately sized float valve con-
nection located in cold water basin. Tower drain and overflow connections
are located on the side of the collection basin. If you wish to pipe overflow
and drain water to a remote discharge point, make those connections also.
12. Attach your warm water return piping to the inlet connection.
Fasteners and components provided by others that are to be attached
to the tower must be compatible with the cooling tower materials—e.g.
fasteners in a stainless steel cold water basin must be stainless steel.
Except for the horizontal components of piping, do not support your
pipe from the tower inlet connection—support it externally.
Normally, one of the following two inlet arrangements is provided:
Bevel and groove distribution connection: This is a factory-installed,
galvanized pipe nipple, extending horizontally from the side of the tower.
It is both beveled for welding—and grooved for a mechanical coupling.
If a weld connection is used, it is recommended that the weld area be
protected against corrosion. Cold galvanizing is suggested, applied ac-
cording to the manufacturer’s instructions.
Protect adjacent areas from excessive heat and sparks during welding
or damage could occur.
Flanged distribution connection: The spray system is fitted with a flat-
face flange connection that conforms to 125# ANSI B16.1 specifications.
A full faced gasket and appropriately sized bolts (by others) must be used
for proper distribution function.
